' p ELECTRICAL CLOTH-CUTTER.

This invention relates to electrical cloth cutters and the object of theinvention is to provide a machine of small and compact design andconstruction adapted to be manufactured at a relatively low cost andparticu-' larly designed to be used to out a comparatively few layers ofcloth, though not expressly limitedthereto.v

One object of the invention s to provide a machine comprising but a fewparts, rigidly and well assembled and well adapted, because of its sizeand compact construction, to delicate or fine work. V

Another object of the invention is to provide a generally improvedelectric cloth cutter. Still another object is to provide mprovedsharpening means for the knife. lVith these and other ancillary ob ects1n view my invention is embodied in acutting machine arranged andconstructed as hereinafter set forth and as illustrated in theaccompanying drawings, in which' Figure 1 is a front view of the machinewith parts omitted and looking in the direction of arrow 1 in Fig. 2;

Fig. 2 is a side view looking in the direction of arrow 2 in Fig. 1;

Fig. 3 is a sectional view taken on line 33 ofFig.2;

Fig. 4 is an end view looking in the direction of arrow 4 in Fig. 2; and

Fig. 5 is a detail view of the sharpening means.

The reference numeral 1 denotes a fiat base having the finished flange 2so that it.w1 ll slide easily over the table. The base is rounded at theedges as at 3, 3 to enable ity an aperture or cut out portion in thewall 5. The bracket 4 is provided with a foot 15 and is secured to thebase by screws 16, 16, see

Fig. 4. 17 is a foot to facilitate the entering of themachine inthe'layers of cloth to be cut and'to gather up, as it were, the layersof cloth against the knife 13. l

The bracket 4 has an upstanding lug 18 to which is secured "theoperating handle 19 and a 'fiber vplug 20 for connection with anordinary plug from a lamp socket. To the v front of the machine the plug20 carriesa lamp-23 for illuminating the work as will be understood. H

,The motor 24 for operating the knife 13 25. The motor shaft26 extendsfrom the hub 27 of the motor and the hub 27 enters the recess 11aforesaid in'the boss 9 to accus rately center the motor and support it.The motor carries a pinion 30 located iii the recess 7 aforesaid'andwhich drives a gear 31 located in the recess 8. The gear 31 runs on abearing 32 on the fixed stud 33. The knife 13 is secured to the gear 31by a screw Cap 34.

The foot 17 is slit as at 35, Fig. 3, to permit passage of the knife andthe base is cut out at 36 for the same purpose. 37 is a lint hole topermit the floss or lint caused by the cutting to pass away from theknife as will be understood. I It will be understood without further description or illustration that suitable electrical connections areprovided leading from the plug 20 to the motor to supply the latter withcurrent. In F igs'. 1 and 2 a snap switch 37 is shown so that theoperator may start and stop the motor.

In order to sharpen the knife there is secured to the bracket wall 5 asmall bracket 40 to which is pivoted at 41 an arm 42 which carries tworotatably mounted abrasive wheels 43, 43. The wheels are held in theposition shown in Fig. 3 across the knife 13 by a spring 45 which pullsthe arm 42 against a stop 46. The bracket 40 extends into the cut outportion 14 in the bracket 4 and the arm 42 is mounted transversely insaid out out portion or opening 14.

When the operator desires to sharpen the knife, he takes hold of thehandle 48 which is on the outside wheel 43 and pulls said handle towardthe knife thereby bringing ear-ear oFE CB Specification of LettersPatent. Patented Sept, 14, 1920. I 1 Application filed a e so, 1919.Sara No. 07,672.

e 10 is secured to the bracket 4 by three screws apart for repairs andthe like. The sharp-' ening means may be made as a unit as shown in Fig.5 and thereafter attached to the ma chine, which, as seen, is'compactand comprises but a few parts. The knife is protected by running in arecess 50 in the bracket and no special knife guard required.

While I have illustrated my invention in its preferred form it will beunderstood that I donot wish to be limited to the precise details shownbut that changes may be made without departing from the principle of theinvention and the scope of the appended claim.

I claim:

In a cloth cutting machine the combination of a base, an upright bracketsecured thereto, 7 a semi circular flange portion formed integral withthe said bracket and extending to the one side thereof overhanging thesaid base, a motor having a hub supported in said'upright bracketfmeansfor securing the said motor to and underneath the said semi-circularflange, which latter serves as a means for partially protecting the saidmotor and its"'said" support in the said bracket, a knife mounted on thelatter on the side opposite the motor, means for driving said knife fromthe motor, sharpening wheels for the knife, sharpening wheels supportingmeans secured'to, the said upright bracket unoerneath the saidprotecting flange, said supporting means projecting through an aperturein said upright bracket to support the said sharpening Wheels inposition to contact with the knife, and means on the outside of saidbracket for operating said sharpening wheels into contact with the saidknife.
